Be it known that I, HENRY C. I IoLrHorr,

2a 'citizen' of the United. States, residing at Riverside, in the county ofCookand State of Illinois, have invented a lcertainnew jand useful Improvement in Timber-Treating Ap paratus, .oic' which the following isaispecifica tlon.

-"' tus, and more particularly to improvements .Tliisinvention relates to improvements in the construction of timber treating apparain the construction of piling. or 'tieica'rs and itoflm' eans for securing the bails thereto. I The object of the invention 1s. to'prov 1de a meansafor securing the bails oftle or piling *cars to the body portions :thereof, which is I simple, in. construction, efiicientin operation," 7 1 and which will permit ready. removal of the the i-drawing accompanying 1 and forming part of this specification, in which likeref -Jerence characters designatethe same o'rusimi- Figure 1 is an end view of'atle car larparts in thefvarions views.- v g i showing the bail and bail arms connected by securing means,abu1ltin-accordance wlth the present I Xinvention; Fig. 2 is-an enlargedscentral ver-' so tical section through a fragmentofthe bail,

tween the members. Fig. is anenlarged finodified form of connection between these membersf The tie or piling car consists essentially of a sheet metal body portion carried by wheels 4: andprovided wit upwardlydirected bailv carrying arms 5, see Fig. 1. The bail-carry- Ifingfarms 2 are also formedof sheet metalv and are provided with reinforcing ribs 5, formed of sheet metal having a U-shaped cross section. Protecting guards qcr plates 3' extend inwardly from the bail-carrying arms 2 and serve as protecting hoods for the wheels 4. The bail 1whichissemicircular in shape, has its ends downwardly directed and extending for a short distance into the ends Jofthe bail-carrying arms2. I n

The securing means between anjend of the bail 1 and a bail-carrying arms 2, consists,

The stop-carrying ,member, 9, which ,is preferably formed eof cast metal, is provided at its lower end zwithin' .wardly projecting-lugs I10, and is adapted 'to fit; snugly into the end of the. bail-carrying arm 2.: The member 9, see Figs? ly ndi2,

spans the interior of thebail-carryingltarm .2 andls .fastened thereto by" means of rivets .12 ,or other suitable fastening: means; The

' end Oftll'e bail-carrying member Qand the stop-carrying; member 9' coaict :so as to. form The hook? is providedwith an inwardly progectmg lower portion-11 which extends under: the lower endof. the member 9.i=iThe ;upper endof the hook lis-zprovided with" a stop 8 which normally coactswithvthe upper end of v.th'e member-- 9, thereby preventing mined position. iThe upper'hooked ortion to take over the link 6'wh1cl1' is mounted upon .the'bail i1' a-nd is v adapted toxkswing outwardly therefrom.

In the modified form of securing means between the bail 1 andabail-carrying: arm 2.

see Fig. 4, the stop-carryingnmember 9 has -,been entirely j 15 spans 1 the interior of? -the'bail-carryir'ig omitted. The transverse E bolt .rnember'2 and-forms a stop for -theendaof the bail 1. The hook 17 is whichv project overthe upper. side edges: ofthe' bail: arm 2, thereby preventing dropping of the, hook 17 by t d d-residenlowets poffthe hook 17 has- 'a projection 19 which extends under the transverse bolt 15, while "the upper hooked portion of the hook 17 takes over the link 6 which is secured to'the bail 1 in a manner-similar to that above disclosed. 1 I

In order to remove the bail 1 from the bail-carrying members 2, it is necessary only to raise the hooks 7 until the portions 11 contact 'with the members 9, and to swing the links 6 on either side of the car" out wardly so as to be free from'c oaction with the adjacent hooks. The bail 1 can then be easily lifted upwardly out of the sockets formedin the members 9, by means of the links 6 which during removal of the bail serve 'as removing handles. In placing the bail 1 in position, the ends of the bail l are inserted into the sockets formed in the mem- .Ja recess into which the end of the bail"; 12 can b freely inserted; I

beyond a predeterprovided with A the portions 11 contact with the lower end's of the members 9 when the links '6 are per:

mitted to swing into contact with the -sides;

of the hooks 7. The hooks 7 are then per; mitted to drop back into the position shown I in Fig. 2 The'insertion and removal of the device disclosed in Figf is identicalwith that just explained, the differences between- ::the devicesof Figsul and'z tbeing structural -=and;not affecting the operation, I a been loaded If the piling car after having withitimber, is placed intofa treating cylinas is customary in the process 0t treating ,rtiinber, the timber has a tendencyto float, thus'tendingto raise the bailsl away from der and submerged in the treating; liquid,v

the car. It will be noted that with the conaftimber treating car,'a"hol-low bail amember extending into the hollow structions' disclosed, such tendency to raise the bails 1 will: cause the hooks 7, 17, tobe drawn upwardly 'untilthe projections 11; 19, r :contactwith the lower surfaces of the member 2 and bolt 15, after which a further rise of the bails 1 is prevented. The projections 11, 119, after removal' of the car from-the liquid, recede from their stops, thehooks again taking the normal positions as shown inthe drawing-. 1
